We install takai quickstart 2.5, but can not display frontpage direcly ( display blank page). frontpage will display when add ..../index.php at the domain link. Please help us to improve the instalation.... www.sitinjaunews.com

Hello,

I see your site is already working properly.
Once you have installed Takai, make sure to update the template to it's latest version and also update Joomla! and K2.

yes, I try to adjust in control panel, make new address for redirects www.expl.com to www.expl.com/index.php. Idont know it was a better choice or not.
Thanks for your response Krikor Boghossian

This is a solution but it should work out of the box.
Make sure that an index.html is not present in Joomla!'s root folder.
